無(wu)軌電(dian)(dian)動(dong)平車(che)制(zhi)造(zao)商表示，如果無(wu)軌電(dian)(dian)動(dong)平車(che)缺相，驅動(dong)電(dian)(dian)機(ji)(ji)所有者和控(kong)(kong)制(zhi)電(dian)(dian)路的電(dian)(dian)器損壞，線(xian)(xian)路斷開(kai)或(huo)(huo)接觸不良，也會使(shi)平車(che)驅動(dong)電(dian)(dian)機(ji)(ji)缺相，無(wu)法正常工作。在這(zhe)種情況(kuang)下，需要對主(zhu)、控(kong)(kong)制(zhi)電(dian)(dian)路進行維護(hu)。在維護(hu)過程中(zhong)，為了防止(zhi)主(zhu)、控(kong)(kong)制(zhi)電(dian)(dian)路給三相電(dian)(dian)機(ji)(ji)的電(dian)(dian)源(yuan)缺相而燒毀電(dian)(dian)機(ji)(ji)，或(huo)(huo)者電(dian)(dian)動(dong)平車(che)驅動(dong)電(dian)(dian)機(ji)(ji)突然通(tong)電(dian)(dian)，造(zao)成危害，需要先(xian)將電(dian)(dian)機(ji)(ji)從電(dian)(dian)源(yuan)線(xian)(xian)上斷開(kai)，只給主(zhu)、控(kong)(kong)制(zhi)電(dian)(dian)路供電(dian)(dian)，然后點(dian)擊啟動(dong)停止(zhi)開(kai)關，檢查分析控(kong)(kong)制(zhi)電(dian)(dian)器和電(dian)(dian)路的工作情況(kuang)，修復或(huo)(huo)更換有問題的電(dian)(dian)器或(huo)(huo)電(dian)(dian)路。只有確認主(zhu)、控(kong)(kong)制(zhi)電(dian)(dian)路無(wu)故障，才能(neng)重新試(shi)運行。

　　減速器(qi)故障：首先關閉(bi)機器(qi)，檢查(cha)內部接觸點是否(fou)有輪滑(hua)油。如果油不足或發(fa)黑，需要更換或加(jia)油。如果長期保(bao)持(chi)，齒輪和齒面會過度磨損(sun)(sun)或損(sun)(sun)壞(huai)。

　　電(dian)(dian)動齒輪故障:立(li)即停止(zhi)軌道電(dian)(dian)動平(ping)車定(ding)制，檢(jian)查電(dian)(dian)動平(ping)車齒輪運行是(shi)否正(zheng)常(chang)，或(huo)齒外表面(mian)是(shi)否損壞，中心軸(zhou)是(shi)否偏離位置等(deng)。，這會使齒輪產生(sheng)異常(chang)噪音(yin)。不(bu)(bu)同故障產生(sheng)的(de)噪音(yin)不(bu)(bu)同。當齒輪運行異常(chang)時(shi)，整個(ge)齒輪噪音(yin)沉(chen)悶；當齒面(mian)損壞時(shi)，噪音(yin)相對清晰(xi)。

　　電控箱故障:噪聲一般以電流(liu)音為主，一般認為電流(liu)接頭(tou)故障或部分(fen)接觸件(jian)老化，應更(geng)換或重新加固(gu)接觸進(jin)行處理(li)。

　　無軌(gui)(gui)電動平(ping)車(che)制造商還提醒您，如果無軌(gui)(gui)電動平(ping)車(che)設備在運行過(guo)程中(zhong)溫(wen)度過(guo)高，軸(zhou)承內的潤滑油將(jiang)失效，添加(jia)潤滑油將(jiang)不方便。這樣(yang)，無軌(gui)(gui)電動平(ping)車(che)將(jiang)長期處(chu)于干磨(mo)狀態(tai)，自然會加(jia)劇軸(zhou)承內部的磨(mo)損(sun)。
